Tracheal bronchus is a aberrant, accessory or ectopic bronchus arising almost invariably from the right lateral wall of the trachea and nay be related to inflammatory conditions affecting the lung, including recurrent pneumonia and bronchiectasis. Recently we experienced a case of tracheal bronchus associated with pulmonary actinomycosis. The 37-year-old male patient had suffered recurrent hemoptysis and had been medicated as a presumptive diagnosis of tuberculosis, but neither clinical nor radiologic improvement was not seen. Right upper lobectomy was performed and pulmonary actinomycosis was confirmed by the histologic examination. Postoperatively, the patient was medicated with penicillin and ampicillin for 3 months and completely recovered without any evidence of recurrence during the 6-month followup period.

Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.

Occult bronchial foreign body is that long-standing foreign body lodge in bronchial tree. A 63-year-old male was admitted our hospital complaining of a cough. Chest computerized tomography and bronchoscopy showed collapse of right middle lobe and foreign body in the bronchus intermedius. After open thoracotomy and bronchotomy, foreign body was removed and collapsed middle lobe was ventilated. Herein we report a case of middle lobe syndrome caused by occult foreign body in the bronchus intermedius.

A 20 year old woman had developed stenosis at the lower part of the trachea, right main bronchus, and right upper lobe bronchus as a complication of endobronchial tuberculosis. The patient had complained of severe dyspnea. Tracheobronchial stenosis was so extensive that we did reconstruction of the trachea and right bronchus with resection of the lower trachea and right main bronchus and right upper lobectomy. She has been doing well without any respiratory symptoms or complications.

The bronchus and alveoli from young rats have been examined by electron microscope following the exposure of cigarette smoking. Experimental animals were exposed to the sidestream smoke in an experimentally designed cage for 45 minutes per day during four weeks. In the smoking group, transmission electron micrographs of lung tissues showed a large number of neutrophils with electron densed several lysosomes, numerous macrophages with many small lysosomes, and many residual bodies in alveolar space. Scanning electron micrographs revealed that the ciliated epithelial cells in bronchus of smoking group were replaced by goblet cells including loss of cilia, and increased cell size of many goblet cells in bronchus. These results depicted that the ultrastructural changes are due to the passive smoking, involving airway cell Injury.

Developmental pulmonary abnormalities are known as rare condition. diagnosis was made at autopsy in the early cases reported, however, as diagnostic aids such as X-ray, bronchography, bronchoscopy and exploratory thoracotomy have come into use, the condition is being discovered more often recently in living persons, and it appears to occur with sufficient frequency to merit consideration in the differential diagnosis of certain chest conditions. According to Schneider and Boyden there are three main types of this abnormality: [1] Agenesis, in which there is complete absence of one or both lungs; there is no trace of bronchial or vascular supply or of parenchymal tissue. [2] Aplasia, in which there is suppression of all but a rudimentary bronchus which ends in a blind pouch; there are no vessels or parenchyma. [3] Hypoplasia, in which the bronchus is fully formed but is reduced in size and ends in a _ flesh structure which usually lies within the mediastinum. Rudimentary pulmonary parenchyma may be present around the bronchial stump and often is the site of cystic malformation. We experienced one case of hypoplastic lung with cystic malformation which was originated from a small aberrant rudimentary bronchus, and the rudimentary bronchus was branched from the right side of tracheal end. The diagnosis was finally confirmed by the histopathological finding. Now, we report this case with a brief review of literatures.

Leiomyoma of the bronchus is a very rare, benign tumor of the lung. We herein report a case of endobronchial leiomyoma which was treated by sleeve bronchoplasty without resection of the lung and without any complications. A 35-year-old man was admitted to our hospital complaining of stridor. Bronchoscopy revealed a round, hypervascular and smooth tumor nearly obstructing the left main bronchus at 1.5 cm distal portion from the carina. Biopsy was not performed for fear of massive hemorrhage. A sleeve resection of left main bronchus including the tumor and end-to-end anastomosis were performed. The histologic diagnosis was leiomyoma. The early diagnosis and appropriate surgical treatment to preserve the pulmonary function are important points of consideration.

Foreign bodies in the air way are not uncommon conditions in the otolaryngological fields. Numerous cases are reported by many authors. This case report is concerned with five cases of various respiratory tract foreign bodies removed under the bronchoscopic control, recently experienced by authors. Case 1; A metal zipper was found at the right main bronchus and was removed by brochoscopy in a 10 year-old-boy. Case 2; A stainless coverage piece of a umbrella was packed at the right main bronchus in the 5-year-old boy and was removed by bronchoscopy. Case 3; A half splitted peanut in the right main bronchus was removed by bronchoscopy in a 18 months-old baby. Case 4; A apple see dcase was lodged in the right main bronchus and was removed by bronchoscopy in a 6 months-old baby. Case 5; A hairpin was also lodged in the right mainbronchus and was removed by bronchoscopy in a 5 year-old boy.

Granular cell tumor(myoblastoma) of the bronchus is an uncommon benign tumor that causes pulmonary complications due to obstruction of the airways. The tumor as origianally described by Abrikossoff was considered to be muscular origin, but currently neural derivation is favored. We report a case of granular cell tumor of bronchus of 27-year-old female patient with recurrent pneumonia that is confirmed by bronchoscopic biopsy, and review the liturature.
